abe.®cote 441 is a protective and decorative coating for steel, concrete and timber.

Uses

Finish coating on various flooring systems. The clear material is suitable for bar counters and similar applications.

Advantages
  • Non-toxic when dry
  • Salt spray resistance (passes 1 000 hours)
  • Weather resistance – does not chalk, white does not yellow
  • Excellent water resistance
  • Resists aliphatic solvents, xylol, alcohol
  • Does not taint water
Surface Preparation

At the time of applying abe.®cote 441 the surface should be clean, mechanically sound and dry. abe.®cote 441 is normally applied over primed surfaces and therefore surface preparation must be consistent with the primer being used. If timber is sealed with abe.®cote 441, it should be sanded smooth and all debris of sanding removed. Oily timbers such as teak should be washed down with pure acetone (oil free acetone) and allowed to dry before coating with abe.®cote 441.

The substrate must be dry before application. Moisture content tests must be conducted prior to application of the priming system e.g. protimeter survey master or equivalent, or dynamic calcium chloride moisture “weight gain” over 24 hours, or a practical overnight “plastic sheet test” is also advisable approximately 1 m² masked own on surface.

Bonding/priming

Dry concrete and other porous surfaces – abe.®cote 386 or abe.®cote 436

• mild steel – abe.®cote 384
• Dry concrete and other porous surfaces – abe.®cote 386 or abe.®cote 436
• timber (under pigmented abe.®cote 441) – abe.®cote 386 ensure the timber is free of natural oils by solvent wiping the surface with oil free acetone and allow it to dry.
• galvanised steel – abe.®cote 386 ensure the timber is free of natural oils solvent wipe the surface with oil free acetone and allow it to dry.

Mixing

Stir the contents of each container, particularly the base, very well. Add activator to base and stir together for at least 5 minutes using a flat paddle. Mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a paddle. If only part of a kit is to be used, add one volume of activator to two volumes of base. Measuring must be accurate and separate stirrers and containers used for proportioning each component.

Allow mixed material to stand for 20 minutes in shade prior to application. If thinning is needed use only abe® thinners no. 2 – incorrect choice of thinners may cause bubbling in the film. If the kit is split and kept for future use, the activator container must be very tightly sealed and stored upside down. The activator will react with moisture in the air. The split kit should not be stored for more than a few days or gelling will occur.

Application

abe.®cote 441 should be applied to the pre-primed surface within the overcoating time stipulated for the relevant primer. If airless spray is used for application a nozzle of approximately 400 μm should be used. Conventional spray is not recommended since any trace of moisture in the air supply may result in bubbling. Bubbling can also result from using damp brushes or short fibre rollers which are not completely dry before use, and also from applying too thick a film of material. Never apply thicker films than recommended.

abe.®cote 441 should not be applied if the ambient temperature is below 8 °C. The curing reaction will not proceed at low temperatures. If the surfaces are not at least 3 °C (preferably 5 ºC) above the dew point there is every chance that a film of condensed moisture could be present. This again will cause bubbling, surface cloudiness as well as compromising adhesion and aesthetics. Do not apply to damp substrates

Cleaning

abe® super brush cleaner before curing.

Protection On Completion

Protect surface against traffic and spillage until cured.

Model Specification

The coating will be abe.®cote 441, a two component polyurethane enamel applied in accordance with a.b.e.® Construction Chemicals’ recommendations.

Packaging

abe.®cote 441 is supplied in 1 L and 5 L yield metal containers.

Handling And Storage

All abe®cote 441 related products have a shelf life of 12 months if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf-life may be reduced.

Health And Safety

Wet abe.®cote 441 is toxic and flammable. Ensure working area is well ventilated during application and drying. Avoid flames in vicinity. Avoid inhalation of dust and contact with skin and eyes. Suitable protective clothing, gloves, eye protection and respiratory protective equipment should be worn. The use of barrier creams provides additional skin protection. If contact with skin occurs, wash with water and soap. Splashes into eyes should be washed immediately with plenty of clean water and medical advice sought. Cured abe.®cote 441 is inert and harmless. When transporting liquids and semi liquids by aircraft, ask for material safety data sheet.
